An exploratory descriptive cohort study of 90-day prognosis after acute ischaemic stroke with mechanical thrombectomy

To evaluate the relationship between nursing assessment findings at discharge and acute ischaemic stroke (AIS) patient prognosis after mechanical thrombectomy (MT).

We analysed the characteristics of 144 AIS patients with MT treatment admitted to a university affiliated teaching hospital in Chengdu, Sichuan Province China, from January 2020 to December 2020. The modified Rankin Scale (mRS) score was used to assess outcomes 90-days after discharge. Exploratory analyses were undertaken using IBM SPSS Statistics (Version 26.0).

At 90-days, 47.9% (n = 69) had a good prognosis (mRS ≤ 2) including 22.2% (n = 32) fully recovered patients. There were 5 (3.5%) deceased patients and 48.6% (n  = 70) of patients had a poor prognosis (mRS ≥ 3). In univariate analysis, clinical prognosis correlated with the need for inpatient endotracheal intubation (p = 0.02), nasogastric tube (p < 0.001), indwelling urinary catheter (p < 0.001), central venous catheter (p = 0.03), health knowledge needs of pressure injury prevention (p = 0.03), National Institute of Health Stroke Scale (NIHSS) score (p < 0.001) and Activities of Daily Living (ADL) score (p < 0.001) at the time of discharge from hospital. The average hospitalization time of the 144 patients was 12[IQR, 9-25] days, and the average cost of hospitalization was $Y$21291.93 (SD 9165.01).

Almost half of the surviving patients had a poor prognosis. In our country, this surgery and rehabilitation impose a significant financial burden that needs to be addressed. However, the longer length of hospital stay and higher costs at discharge may be contributing factors to worse outcomes. The outcomes of comprehensive nursing assessment of the patients, including nursing needs, activities of daily living, and neurological function, can predict their outcome.

We recommend a comprehensive nursing assessment at discharge that predicts patient outcomes and can be used for subsequent targeted interventions. The prognosis of patients with acute ischaemic stroke after mechanical thrombectomy is poor, and the financial burden needs to be considered.
